认知神经心理学理论研究与失语症治疗的关系

该文介绍了词语产出的加工阶段以及在获得性语言障碍病人（失语症病人）身上这些阶段可能的损伤情况。文中特别介绍了两例词汇提取障碍病人的治疗,这不仅有助于了解该障碍,更有助于了解其潜在的理论问题。第一个案例关注使用不同的任务治疗词汇提取障碍,评估治疗效果,探究任务产生作用的原理。第二个案例使用词汇提取障碍的治疗方法探讨一个充满争议的问题：同音词（如,pour/paw）在词汇产出过程中是共用一个语音表征还是各自单独表征     

Assessing students' use of optional online lecture reviews

Online practice quizzes can be used to supplement instruction in the classroom. Such quizzes can engage retrieval practice, thereby improving learning and retention. However, despite their potential benefits, recent work suggests that students typically underutilize online practice quizzes. This article reports an observational classroom study, in which students were provided optional online reviews throughout the semester. The reviews could be accessed in test format, in which students were given multiple-choice questions and provided correct answer feedback, or in read format in which students were given the same questions and were shown the correct answers. Students who used the test format performed better on exams than students who used the read format or did not use the reviews. Nevertheless, the massive majority of the online reviews (approximately 88%) were not completed, highlighting the tendency for students to underutilize optional online reviews.     

Improved classification of mammograms following idealized training

People often make decisions by stochastically retrieving a small set of relevant memories. This limited retrieval implies that human performance can be improved by training on idealized category distributions (Giguère & Love, 2013). Here, we evaluate whether the benefits of idealized training extend to categorization of real-world stimuli, namely classifying mammograms as normal or tumorous. Participants in the idealized condition were trained exclusively on items that, according to a norming study, were relatively unambiguous. Participants in the actual condition were trained on a representative range of items. Despite being exclusively trained on easy items, idealized-condition participants were more accurate than those in the actual condition when tested on a range of item types. However, idealized participants experienced difficulties when test items were very dissimilar from training cases. The benefits of idealization, attributable to reducing noise arising from cognitive limitations in memory retrieval, suggest ways to improve real-world decision making.     

Information presentation format moderates the unconscious-thought effect: The role of recollection

The unconscious-thought effect occurs when distraction improves complex decision-making. In two experiments using the unconscious-thought paradigm, we investigated the effect of presentation format of decision information (i) on memory for decision-relevant information and (ii) on the quality of decisions made after distraction, conscious deliberation or immediately. We used the process-dissociation procedure to measure recollection and familiarity. The two studies showed that presenting information blocked per criterion led participants to recollect more decision-relevant details compared to a presentation by option. Moreover, a Bayesian meta-analysis of the two studies provided strong evidence that conscious deliberation resulted in better decisions when the information was presented blocked per criterion and substantial evidence that distraction improved decision quality when the information was presented blocked per option. Finally, Study 2 revealed that the recollection of decision-relevant details mediated the effect of presentation format on decision quality in the deliberation condition. This suggests that recollection contributes to conscious deliberation efficacy.     

Ease‐of‐retrieval effects on procedural justice judgements under conditions of informational and personal uncertainty

This study tests whether individuals' reliance on ease‐of‐retrieval processes when forming procedural justice judgements are moderated by informational and personal uncertainty. In Studies 1 and 2 we examined the predicted effects of informational uncertainty. Results indicated that participants in information‐uncertain conditions relied on ease‐of‐retrieval, whereas those in information‐certain conditions relied on content information to make procedural justice judgements. In Study 3 we examined the combined effects of informational uncertainty and personal uncertainty on reliance on ease‐of‐retrieval when forming procedural justice judgements. The findings of Study 3 indicated that personal uncertain participants who were in informational certain conditions based their procedural justice judgements on content information, whereas all other participants based their procedural justice judgements on ease‐of‐retrieval. This is the first paper to demonstrate that the joint effect of informational uncertainty and personal uncertainty on reliance on ease‐of‐retrieval is different from the two uncertainties acting alone.     

无意识思维:理论、质疑与回应

Dijksterhuis等人发现在解决复杂问题时,无意识思维的加工结果优于有意识思维,并据此提出了无意识思维理论。本文介绍了支持无意识思维理论的基本实验证据,质疑无意识思维的相关研究及对质疑的回应研究。未来研究应重点关注改进无意识思维研究范式和寻找更多影响无意识思维效应的中介变量,无意识思维加工结果如何上升到有意识层面,无意识思维的加工方式以及其在真实和高风险任务情境中的应用。     

Understanding the underlying mechanism of the spacing effect in verbal learning: a case for encoding variability and study-phase retrieval

The spacing effect refers to the mnemonic benefit of spacing repeated study events across time compared to massing (i.e. cramming) repeated study events. Due to the robustness of this finding, substantial research has been devoted to uncovering the spacing effect’s underlying mechanism. Specification of such a mechanism has been guided by consistent findings across methodologies and several experimental manipulations that serve as boundary conditions. Past reviews of the spacing effect literature have generally considered subsets of these factors but never an exhaustive set. Thus, the current review considers more comprehensively six consistent findings in the extant spacing effect literature pertaining to human memory to better discriminate among the previously proposed theories. Review of the literature provides substantial evidence indicating the need for an encoding variability mechanism [e.g. Glenberg, A. M. (1976). Monotonic and nonmonotonic lag effects in paired-associate and recognition memory paradigms. Journal of Verbal Learning and Verbal Behavior, 15, 1–16] in addition to a reminding mechanism [e.g. Benjamin, A. S., &; Tullis, J. G. (2010). What makes distributed practice effective? Cognitive Psychology, 61, 228–247].     

特征整合与加工深度对道德概念容器隐喻联结的影响

提出了隐喻提取假说将隐喻联结的形成和提取进行分离, 并通过3个实验探究了道德概念与容器空间的隐喻联结及其受知觉加工深度和特征整合程度的影响。实验1采用空间Stroop范式, 实验2a和实验2b均采用启动范式, 实验3a和实验3b均采用加入任务要求的Stroop范式。结果发现：(1)在经典Stroop范式中未发现道德概念与容器空间的隐喻联结; (2)在启动范式中发现, 较深知觉加工深度下道德概念与容器空间存在较弱的隐喻联结; (3)在较高特征整合程度的Stroop任务中, 道德概念与容器空间存在较强的隐喻联结。结果表明：道德概念与容器空间存在道德为内、不道德为外的隐喻联结, 这种隐喻联结在映射上表现为双向性, 并且受到特征整合程度和知觉加工深度的影响, 同时也为隐喻提取假说提供了证据支持。     

编码和提取水平对儿童绑定加工发展的影响

将情景中的各要素绑定加工成连贯的关系结构,是形成情景记忆的核心过程。本研究使用图像配对联想学习任务,在测试阶段采用自由回忆、线索回忆和再认任务,考察了儿童二元和三元绑定能力的发展及其中编码和提取能力的影响。结果表明,绑定加工能力随年龄增长而提高,二元绑定比三元绑定的发展开始得更早。编码水平对两种绑定能力存在不同影响,5岁儿童已经具有成熟的编码信息进行二元绑定加工的能力;但三元绑定受限于编码缺陷,在6.5岁后才因相应编码能力的缓慢提高而得到少量发展。但在儿童期内,二元和三元绑定同时受到了提取能力发展的促进。
